So what valor farming techniques have people developed so far? I've gotten 1600+ comms in a couple days on one of my toons.
I've been concentrating on farming short EEs, though I think I'm going to start mixing in EH runs of the same immediately after. Here's the cycle I've concentrated on so far (I don't remember how many comms drop on some since I don't keep track).
The Snitch (EE = 20 comms)
The Last Stand
Claw of Vulkoor
Fathom The Depths
Tharask Arena (EE = 30 comms)
The Prisoner (EE = 30 comms)
Trial by Fury (EE = 40 comms)
Deal and the Demon (EE = 40 comms)
Reclaiming the Rift (EE = 40 comms)
Running a EE Demonweb is always somewhat problematic because of the time is takes people to get to the quest, but it does net 120 comms and moves quickly once you get started. Some are easier to repeat on EH than other because the quest giver is right outside. Of course, at some point I start running out of short quests within the 18 hours and then have to look at the longer stuff to run. I've also picked up a number hopping onto other's EE runs of longer content, which varies in length depending on the group involved.
There's some other quests I haven't tried comm farming, but can be run quickly (will add to as I think of more):
The Tracker's Trap
A Break in the Ice
A Lesson In Deception
The Thrill of the Hunt
Bargain of Blood
Army of Shadow
As one side note, I've started getting way more pieces to complete Epic Red Fens gear.
As a second side note, it makes me wishful Turbine will Epic-fy the Inspired Quarter content since those are fun and generally short quests.
Current best effiency stats on quests I've actually tracked so far (all are based on 28lvl toon at cap, with random pug joiners):
